Trying to add a new AV engine

Hi.

I am trying to add a new AV engine to 15-av_scanners but I am really lost
at the moment configuring the output. Could you help me?

First of all, this is the output with a clean email:

root@correo:~# drweb-ctl checkmail clean_email
/root/clean_email - Ok
Scanned objects: 1, scan errors: 0, threats found: 0, threats neutralized:
0.

And then, with infected one:

root@correo:~# drweb-ctl checkmail infected-mail
/root/infected-mail - Reject
/root/infected-mail//1/Webex.xls (application/vnd.ms-excel): infected with
Exploit.Siggen3.28448
Scanned objects: 1, scan errors: 0, threats found: 1, threats neutralized:
0.
Scanned 194.62 KB in 0.03 s with speed 7208.22 KB/s.

I am trying to configure with:

### http://www.drweb.com/
['Dr. Web Security Space ',
'drweb-ctl', 'checkmail {}',
qr/^Reject/m,,
qr/^(?:infected with:\s+(.+)/m ],

But there is an error with this output:

Could you help me with the output configuration? Thanks in advance.
